Abstract: 531,762. Detecting faults. GENERAL ELECTRIC CO., Ltd., CROFT, E., H., and RANDALL, H. July 24, 1939, No. 21478. [Class 37] In a trolley bus in which electrical apparatus is insulated from the chassis by double insulation, the neutral conductors between the primary and secondary sets of insulation are connected to a testing point so that both primary and secondary sets of the insulation may be tested. The leakage testing equipment for a trolley bus supplied with D.C. from trolley wires 1, 2, the negative wire 2 being earthed, comprises a socket element 3 on the bus and a plug element 4 at the testing station. Some of the electrical apparatus of the bus is provided with double insulation, the secondary sets B of which comprise porcelain insulators for insulating the frames C, of the apparatus from the chassis 31, the apparatus being insulated from the frames by the usual primary insulation A. The socket element 3 comprises eight fingers 20 ... 27, six 21 ... 26 of which are connected to apparatus frames, the remaining fingers 20, 27 being connected to opposite sides of the positive live switch 7 with the interposition of a high resistance 28 between the fingers 20 and the power circuit. A contact 29, adapted to engage a contact 30 on the plug element 4, is connected to the chassis 31. The plug element 4 has six contacts 32 ... 37 connected together and arranged to engage the fingers 21 ... 26, and two contacts 38, 39 connected together and arranged to engage the fingers 20, 27. When the plug is inserted, all the frames C are connected together, the switch 7 is bridged by the high resistance 28, and the contact 30 is connected to the chassis. A milliammeter 47 is connected between the contact 30 and earth and indicates any leakage from the power circuits to the chassis. By depressing a pushbutton 48 the secondary sets of insulation B are short-circuited and a leakage test is obtained across the primary sets of insulation A. By depressing a second push-button 49 the primary sets A are short-circuited and a test is obtained across the secondary sets B. In a modification the testing connections are made by a drum switch on the bus.

Title: Improvements in and relating to systems of electric motor control
IPC: H02P5/50
Filed: 1929-07-12
Abstract: 334,014. British Thomson-Houston Co., Ltd., and Pool, W. J. July 12, 1929. Maintaining proportional speeds.-In a motor control system in which a follower motor 2 is regulated by a synchronous dynamometer-type regulator 3 supplied with alternating current at a frequency proportional to the speed of the master motor 1, the current for the regulator is obtained through slip-rings 11 fed from tappings on the armature winding of the master motor. The armature 7 of the regulator is driven by a belt 5 and cone pulley 4 driven by the motor 2. The field magnet system 8 is connected to a device for controlling the speed of the motor 2, such as a rheostat. When two or more followers are to be regulated the motors 3 may be connected in parallel or series. In the former arrangement the leads to the regulating motors are in parallel with the leads from the slip-rings on the master motor and in the series arrangement the first motor 3 is connected directly to slip rings on the master motor, the other regulating motors being fed from slip-rings on the preceding follower. A certain amount of shunt field speed regulation may be used on the master motor. Specifications 181,619, 210,229, 216,871, and 265,995 are referred to.

Title: Improvements in washing artificial silk skeins and other similar material
IPC: D01D10/04
Filed: 1928-07-26
Abstract: 318,715. Bate, D. F. July 26,1928. H a n k type apparatus; spraying travelling materials, -Skeins of artificial silk &c. 31 are carried by radial arms 30 carried by a central rotating member 12 which supports a liquor reservoir 10 from which liquor is sprayed by radial supply pipes 33, 34. The member 12' is carried by a shart 13 driven from a shaft 14 through worm gear 15. Parallel to the shaft 14 is a second shaft 16 which is driven through gearing 17 when a dog clutch 18 is engaged. This clutch is alternately engaged by means of a spring 19 and disengaged by a rod 20 engaging cam faces 21 on the wormwheel 15. The shaft 16 drives, through bevel-gearing 32. 28, a hollow shaft 24, and bevel-gearing 27, 29, a series of short spindles 28 adapted to carry tubular capstan arms 30 from which the skeins 31 are hung, the skeins being if necessary weighted by bottom bars 32. The tank 10 is divided into compartments by radial divisions, each compartment being provided with a delivery pipe 35 having two arms 33, 34 provided with perforations which project above and on each side of each capstan arm 30. The tank 10 is supplied with liquid from one or more pipes 9, 39, 40, each supplying the compartment below it. When the clutch 18 is disengaged, the bevel-wheel 23 remains stationary and the spindles 28 are rotated by the bevel pinions running on the wheel 27. When the worm-wheel 15 has rotated sufficiently to allow the clutch 18 to engage, the bevel-wheel 27 is rotated faster than the member 12, so that the direction of rotation of the spindles 28 is reversed. The spindles 28 carry projections 38 engaging arms 36, 37 on a cock 35, so arranged that liquid is supplied to one of the arms 33, 34 according to the direction of rotation of the spindles 28, and therefore of the capstan arms 30, so that the liquid is sprayed on the rising sides of the skeins at a, gentle angle so as not to injure the fibres. Alternatively, a single spray pipe may be employed for each capstan arm and may be pivoted or turned to produce the same effect. According to the Provisional Specification, belts may be employed instead of bevel-wheels.

IPC: H01L21/223
Filed: 1962-06-07
Abstract: <PICT:0987895/C1/1> A semi-conductor device is formed by depositing layers of semi-conducting material from gas phase on to a heated mono-crystalline semi-conductor base having substantially the same crystal lattice structure as the deposited coating, but of different conductivity and/or doping concentration, the mono-crystalline base being formed as a plurality of substantially parallel and integrally joined wafers.  For example, a bar of silicon or germanium, Fig. 2, has a number of slots 0.3 mm. wide or more sawn at right angles to the axis of the crystal; the slots may be on alternate sides as shown, or all on the same side.  The crystal may be heated inductively or directly, assisted by inserting a plate of Mo or W between two of the wafers. The wafers may be coated on one or both sides to form PNP or NPN devices. Doping materials e.g. B or P chlorides may be added to the gas mixture e.g. of Si or Ge tetrachlorides and hydrogen, and the proportions may be varied during deposition.  The semi-conducting materials deposited may be Si, Ge, In, and arsenides or phosphides of Al, Ga, or In.  A number of combinations and multi-layers are described. The coated wafers are finally separated by cutting the crystal in its longitudinal axis.
